WINDOW-SCREEN.

' Specification of Letters Patent.

Patented Dec. 26, 1905.

To all whom it may concern.-

Be it known that I, RICHMOND PARSONS, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a novel construction of a Screen, of. which the following is a specification.

My invention consists of a window-screen which is provided with guards for the spaces between the sides of the screen proper and the sides of a window, so as to prevent the entrance of insects at said spaces, novel means for connecting the lower portion of the guides or guards with the casing on which is mounted the screen-roller, and novel means for automatically securing the casing on a windowframe. 7

Figure 1 represents a perspective view of a window-screen embodying my invention, certain portions for clearness of illustration being omitted. Fig. 2 represents a vertical section on line w m, Fig. 3. Fig. 3 represents a broken front elevation of a lower portion of the device. Fig. 4 represents a perspective view of the end of the roller-support. Fig. 5 represents a perspective view of the clip or fastener employed.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates a piece of gauze or netting constituting the screen proper, the same being connected at one end with what is known as a springroller 2. At the top 3 of said screen is attached the fastener 4, comprising a piece of metal bent upon itself at any point 5, one portion 8 of which contains an opening 6, adapted to engage the pin or hook 7 on thelower part of the sash 10. The other portion is bent up from said portion 8 to form a finger-piece 9 for conveniently attaching the screen to and detaching it from the sash, it being evident that the roller 2 is adapted to wind or unwind the screen in accordance with the movements of the sash.

11 designates a casing having a flat bottom 12 and sides 13 and 14 at right angles thereto. This casing is formed, preferably, of sheet metal, and the upper edges of said sides are inwardly turned at 15 and 16, respectively. Each end of the casing is formed by a threesided strip 17, the fiat bottom sides 18 of which are riveted to the bottom 12 of the casing at points 19 and 20 in such position as to leave room between the upwardly-projecting side piece 21 and the side 13 for the passage of a portion of the guide 22, hereinafter described.

The third side 23 of strip 17 constitutes an end or closure for the casing, the left-hand side having a circular opening 24, as shown in Fig. 4, while the right-hand side has an angular opening 26, as shown in Fig. 1, for controlling the gudgeon of the spring-roller.

Fig. 4 is reversed, showing the rear portions of the casing at the front. I

In order to close the spaces between the sides of the screen and the sides of'the window, I use the grooved upright guides or guards 22, one of which is located upon each side of the screen. Each guard is fitted into the end of the casing by the insertion of the lower end of thelimb 27 of the guard between the side 13 and side piece 21 of the casing 11. The other limb has its lower portion bent outwardly, as at 29, and its lower end 30 fitted over the side 14 of the casing when the parts are in assembled position. This guard 22 is free to move longitudinally of the casing containing the roller with its side 22 between side 13 of said casing and side piece 21 of the end piece thereof, the projecting end 30 of the side 28 being constantly in contact with side 14 of the casing. The opposite side guard is like guard 22, except that, as in the case of the end piece of the casing, each is the reverse upon one end of the casing of that upon the other.

The guards are secured to the sides of the window by means of clips 31, consisting of flat plates 32, having projecting spurs 0r ears 33, which pass through openings 34 in the limbs 28 of the guards, and are bent toward each other inside said guards, retaining the clips in close contact with the adjacent limbs of the guards 28. One edge of each of said plates 32 is bent outwardly at 35 and provided with an opening 36, permitting the passage of a screw or pin whereby the plate may be secured to the side of the window.

So far as described thecasing carrying the roller and screen would be free to move longitudinally within guards 22; but inorder to center the casing on the sill of the windowframe I employ springs 38, which are secured to the guards 22 and press laterally against the pieces 23 of the casing 11, as at 12, thus properly setting or centering the casing-a feature of importance Where window-frames are of different widths. The casing may, however, be made a tight enough fit upon the guards 13 and side members 21 to permit of original adjustment of the casing between the guards and retention of said casing in this position by the frictional engagement thus formed.

It will be evident that various changes may be made by those skilled in the art which Will come Within the scope of my invention, and I do not, therefore, desire to be limited to the exact construction herein shown and described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a window-screen, a casing carrying a see ,aoo

roller-screen, side guards therefor and automatic means for centering said casing.

2. In a Window-screen, a casing, side guards therefor, and automatic means carried by said guards for centering the screen in windows of difierent widths.

3. In a window screen, a casing, side guards therefor, and means carried by said guards for retaining said casing and centering the latter on a window-frame.

4. In a window-screen, a casing carrying a roller-screen, side guards therefor, and centering-springs upon the side guards making contact with the casing.

5. In a window-screen, a casing carrying a roller-screen and automatic means for centering said casing on a Window-frame.
